No. SWAG lists different numbers for the lighter weights: the 15 lb SWAG APEX Pearl is 2.500 RG and .042 differential, while the 13 lb is 2.580 RG and .036 differential and the 12 lb is 2.580 RG and .015 differential. Those are the numbers of a different core shape, and the lower differential means less track flare, so the 12 and 13 lb roll smoother and hook less than the 14 to 16 lb. The full table is on the product page.
